LOOM.

SPECIFICATION forming part of Letters Patent No. 319,475, dated June 9, 1885.

Application filed June 23, 1883. (N model.)

To all whom it may concern.-

' Be it known that we, GEORGE W. FRENCH and JACOB A. MATTERN, of Colfax, in the county of Jasper and State of Iowa, have invented an Improvement in Looms, of which the following is a specification.

Our invention consists in the construction and combination of devices hereinafter de' scribed, and pointed out in the claims. 7

1o Figure 1 of the accompanying drawings is a perspective view of our loom; Fig. 2, a side view; Fig. 3, a transverse sectional view in which part of the frame and the take-up are left off. Fig. 4 is a transverse section of the r 5 shuttle-race, showing a shuttle and the bobbin connected therewith. Fig. 5 is a transverse section of one end of the batten. J ointlyconsidered,these figures clearly illustrate the con struction and operation of our complete inzowention.

A A are the corner-posts of a frame that may be made of wood or metal.

B, B, and B are side pieces in the frame.

0 is the driving-shaft, mounted in bearings 2 5 attached to the side pieces B. l

1 and 2 are treadles or levers of the third order, pivoted to the cross-piece at the front end of the frame, and extending under the heddles at the rear of the frame.

0 d d are heddles, suspended by cords d,

passed over pulleys or the roller d, and connected with the free ends of the parallel levers 1 and 2 by means of cords d. g I

3 and 4 are cams that extend in opposite 3 5 directions from the shaft 6 in such positions relative to the levers 1 and 2 that the cams will alternately engage and depress the levers at every revolution of the shaft, as required, to impart reciprocating vertical motions to the heddles, and thereby raise and lower the threads of the warp passed through the bed dles' f is the batten-beam. It is solid in its cen* tral portion andbifurcated at its ends.

5 f are vertical pieces or swords fixed to the solid portion of the horizontal beam f at their top ends, and to a cross piece or shaft, f, at their lower ends. The complete batten-frame thus produced is pivoted to the side pieces B in such a manner that the batten can vibrate within the central portion of the loom frame.

5 and 6 are arms that projectin opposite directions from the driving-shaft 0. Each arm carries a roller, f at its end in such a manner that the rollers will alternately engage the vertical pieces f of the batten-frame at each revolution of the shaft, as required, to press the same rearward.

A spring, f', has one end connected with the loom-frame and the other with the batten, to draw the batten forward to beat up the weft or woof thread into the angle of the shed in the warp after the batten has been freed from the arm 5 or 6.

g g are straight pieces fixed in parallel po sition upon the top of the solid central por" tion of the batten-beam f, as clearly shown in Fig. 4., to produce a shuttle race. These pieces 9 have flanges g at their top edges, that extend inward and toward each other. They also have coinciding transverse slots g, adapted to receive the warpthreads and to perform the functions of a comb or reed.

h is a shuttle provided with flanges h at its 7 5 bottom edges, that will underlap the flanges g in the shnttte-race and prevent any upward motion or escape of the shuttle as 1 itwslides back and forth within the race. The shuttle carries a bobbin, h, that is journaled to its top and center by means of a detachable screw-bolt, h that is passed down-through a bore in the axis of the bobbin into a nut, h, fixed in the shuttle'body or in any equivalent way. 8 5 h is a light metal plate fixed on the top of the solid shuttle-body in such a manner that it will extend over the slotted top surfaces of the parallel pieces 9 g, and readily slide thereon.

h is a fender fixed to the plate h, and arched over the bobbin h", to prevent warpthreads from catching on the bobbin as it passes through the shed in the warp.

k k are straight bars having flanges It at their. innerltop edges,fixed in parallel position on the top sides of the bifurcated ends of the batten-beam f.

7c are blocks fitted to the slide between the pieces k k. [00

k are flat plates fixed on top of the blocks to form shuttle-drivers.

Z Z are springs fixed to the inner ends of the blocks is and to the batten-beam f in such a manner that the springs will, in their normal condition, retain the blocks and shuttle-drivers at thein'ner ends of the parallel pieces la la.

Z are cords fixed to the outer ends of the blocks 70."

Z are pulleys in the bifurcated ends of the batten-beam f, and Z are pulleys on the under sides of the same beam, over which pulleys the cords extend to be connected with the free ends of levers m, that are pivoted to the frame.

7 and 8 are arms projecting in opposite directions from the driving-shaft 0. They have rollers attached to their ends in such a manner that the rollers will engage the top surfaces of the levers m, and depress these levers alternately at each revolution of the shaft 0. As each one of the levers m is thus depressed, it will draw the cord Z outward over the pulley Z, and thereby move the shuttledriver 7c 70' outward and stretch the spring Z, and by so doing store power in the spring.

m are levers pivoted to the side and opposite ends of the batten-beam f, and connected at their free ends with the levers Nos. 1 and 2, by means of cords m, in such a manner that they will be alternately pulled down to withdrawlatches m, that are pivoted to the levers m, and project up through bearings formed in the pieces 7c. Theselatchcs engage and retain the shuttle drivers at the outer ends of their tracks until the levers m are depressed, when the power stored in the springs Z is permitted to be exerted to throw the shuttle-driver inward, as required, to force the shuttle to the opposite side of the loom through the shed of the warp-threads. This operation of the shuttle occurs at every half-revolution of the 'driving'shaft O, and in concert with the intermittent motions of the reciprocating heddles 'andthe vibrating batten.

m are springs fixed to thebatten in such a manner that they will, in their normal condition, hold the latches m upward.

N represents an auxiliary connected with the loom-frame to support and carry. a roller, 0, upon which the chain or warp threads are wound, to be drawn off at regular intervals by the action of the take-up mechanism, hereinafter described. Series of perforations through the side bars, N, and pins or bolts passed through the posts of the 1 V loom-frame'into those perforations, as showng in Fig. 2, or other suitable equivalent means, i may be used for 'adjustably connecting the,

frame N with the loom-frame.

P is a roller mounted at the opposite end of 3 0." 1s a Q ratchet-wheel fixed on the end of the axle of the loom to take up the woven fabric.

the roller P.

frame adj ustably sis a bent rod, pivoted to the lower portion of the frame in such a manner-that it will extend over the driving shaft 0 and to the ratchet-wheel r, to engage the teeth of that wheel.

.9 are cams on the opposite sides of the shaft 0, that alternately engage the rod 8 and cause it to perform the function of a pawl and to move the ratchet-wheel 1 and roller P at regular intervals, as required to automatically take up the woven fabric.

From the foregoing detailed description of 7 5 the construction and function of each element and sub-combination the unitary actions of all the parts and the practical operation of the complete loom will be obvious to persons familiar with loom mechanism.
